v ELETRICALLY-HEATEDSTEAM BRUSH.

Application. filcdDecember. 831924. Serial No. 754,658.

One object of my invention isto provide inA a steam brush, self-contained means for superheating` steam admitted to the brush.

Another object is to provide'electrically i heated means for drying' tlie, steambefore it is passed out of the body of the brush." Another object is to provide an electrically heated plate for a brush with means for causing the steam passing @i be held in intimate contact with a maximum amount kof the heated surface of the plate.

lith these and incidental objects in view, the invention consists of certain novel features of construction and combination of l5 parts, the essential elements of which are hereinafter described with reference lto the drawing which accompanies and formsV a ypart of this specification.y In the drawing, Figure on the line 1-1 Figure 2. Figure Q is a section taken on the line .Q -2, Figure 1. Figure 3 is an enlarged sectional detail of one of the steam nozzles and Figure 4 is a plan view of electrical heating element.

As shown in the dra-wing, the platel has 1 is a` section taken an electrical heating element 2, carried on' the top surface thereof and insulated there* from by the corrugated asbestos 3 is a cover plate 4. The plate 1 pending therefrom,

with slight clearance, ,by the bristle plate 7. Y

The bosses 6 have nozzles 8 therein, preferably projecting downwardly below the lower surface of the plate 7. Y rlhevcover plate 4 is attached to the vvplate 1 in any suitable manner andv the bristle plate 7 is joined to the plate 1 by screws 9 clamping a steam tight gasket 10 between the plates, y rllie heating element isv brought out through suitable terminals 11 and steam is admitted into the steam chamber k12 through the tube 13 and aperture 14. f

It will be apparent admitted to the steam chamber 12 inr order to pass therefrom, it must pass between the walls of the cup 5 and,l the exterior surface of the boss V7 and as the clearance therebetween is sliglit,`the steam passing'through this tortuous passage is has a plurality of cupsr ldewliich receive therein ture bv the element Fr' 'y 0') thru .the nozzles 8, which. are distributed among the bunches of bristles as sh'own andv thru the brush to" the bosses 6, carried that when steam is Y greatly heated by the plate 1, which is raised toV a high tempera@` 2. The steam passes out as thesteamhas beenexposed to the surface ofthe heating plate 1, it is thoroughly dried before it escapes to the bristles. f

.I ani aware thatl steam brushes have been usedf'in the past, but the contained means for insuring the-delivery of '6o difficulty has been inhavilnggthe steam sufficiently dry to be properly used, asit' tends to condense in the dry steam to the brush bristles and especially believe myself to be the first to have devised electrical'means for thus drying and superheating lthe steam.

lVhile Ihave described my invention and illustrated it inone particular design, I do not wish it understood that I limit myself to this construction, as it is evident that the application of the invention may be varied in many ways within claims.: i

Claims: 1. In a brush the scope of the following ythe combination including a bodyk having a heating chamber and a fluid distributing chamber,- a heating element within the heating chamber, bristle tufts carried by the body,

contained withinthe fluid distributing chamber and communicatingwith the bristles, a

series of cups disposed over the bosses, so as a series of perforated bosses.,V

to form annular restricted passages tlierev with, and adapted .tobe heated by the heatf ing element, whereby'thefluid in the distributing chamber will be heated before being discharged into the bristles.

' 2. In a brush,'the lcombination including a body having afluid` inlet, and having a fluid distributing chamberA communieating therewith and al heating chamber parallel with and adjacent thereto,- Va heating element I within the heating chamber, said heating chamber extending substantially throughout the lengtli'and breadth of the body, bristle tufts carried byfsubstantially the entire face of the ',body,

ing perforations, at intervals between the. tufts, foi' discharging the fiuid,vand heat eX# said bristle. carryinglface hav'- change means within .the-iiuid distributing chamber, uniformly heated by said heating lengthening the course of the chamber, for fluid from the saidtfluid inlet to the said perforations.

` 3. In a steam brush, a brush back of means the combination with for heating said joined to said heating brush back, a bristle plate associatedwith said brush back and forming therebetween a steam chamber, cups depending fromk said brush back, bosses on the interior surface of said bristle plate registering in said cups with slight clearance therebetween and noz*- zles extending through said bosses.

4:. In a steam brush, the combination with a heating plate of an electrical heating unit for said plate, a plurality of cups depending from said plate, a bristle carrying plate plate inv steam tight manner, a plurality or upwardly extending bosses carried by said bristle-plate concentrically positioned within said oups with slight clearance therebetween,

nozzles extending through said bosses and bristle plate and means for admitting steam between said plate and said bristle plate whereby it may pass through tortuous passages between the interior walls of said cups and the exterior walls of said bossesand thru said nozzles.

5. In a steam brush, the combination including a brush back having a heating element contained therein, a plurality of oups depending from the back, a bristle carrying plate joined to but spaced from the back to form achainber therebetween, said platebeing provided with nozzle forming bosses which register and forni restricted passages with Vsaid cups.V
